Abstract (en)

[origin: WO2018051217A1] This invention relates to a process for treating a substrate made of stone material, preferably in the form of slabs, which process is intended to improve the mechanical, thermal and catalytic properties of said substrate. The process according to the invention provides for applying a protective coating to the outer surface of the substrate made of stone material and, in order to improve the adhesion of said protective coating to the outer surface of said substrate, it further provides for preliminarily subjecting the substrate made of stone material to be coated to one or more "pre-treatment" steps that allow to eliminate - or at least reduce - the presence of pollutants and porosity on the surface of said substrate. According to the invention, said "pre-treatment" of the substrate made of stone material comprises at least one step of treatment under vacuum conditions inside an autoclave, preferably under pressure conditions lower than 10-2 mbar. Then, after having brought said substrate back to ambient pressure, it is possible to apply and effectively adhere the protective coating to the surface of the stone material.
